Analysis of Energy Detection Over Cascaded Nakagami-m Fading Channels
نویسنده
چکیده
In this paper, the problem of spectrum sensing using energy detection over cascaded Nakagami -m fading channels was addressed where all terminals are considered as vehicles. Closed-form expressions of detection probability were derived based on probability density function method. The validity of theoretical analyses was shown by comparing numerical results with Monte-Carlo simulations. The results indicate that the detection performance for cascaded Nakagami-m fading is even worse than the conventional Nakagami fading, which can be improved by diversity. © 2014 The Authors.

In this paper, we provide a unified analysis for wireless system over cascaded fading channels modeled either by cascaded Nakagami-m or Weibull fading models. These cascade fading models are developed by the product of independent Nakagami-m or Weibull random variables, which are not necessary identically distributed. The performance measures such as amount of fading, average bit error rate, an...

In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...
